14. Lighting
Incandescent:
• Filament is heated to incandescence by
an electric current, producing visible light
• 5% of energy makes useful light.
• Very inefficient: 15 lumens per watt
• Lamp life is about 2,000 hours
14

15. Lighting
Compact fluorescent:
• Excited gas produces light
• Efficient: 50-100 lumens per watt
• Lamp life is about 8,000-10,000 hours
• Specialized Disposal

16. Lighting - Retrofitting
Retrofitting Incandescent with CFLs
• Rule of thumb of 4:1 for can be applied when replacing incandescent bulbs with CFLs.
• 40-watt incandescent = 10-watt CFL
• 60-watt incandescent = 15-watt CFL
• 75-watt incandescent = 19-watt CFL
• 100-watt incandescent = 25-watt CFL
• CFLs produce 75 % less heat than Incandescent and cut home cooling cost.

18. Insulation
• Heat flows naturally from a warmer to a cooler space.
• Insulation in your home to provide resistance to heat flow.
• Heat flows through wherever there is a difference in temperature:
• Ceilings
• Walls
• Floors
• Crawlspaces
• Windows
• Doors
• More insulation means more energy savings.
• Insulation measured with an ―R‖ value.

19. Building Envelope
Air Leakage
• Leaking air into the home is called infiltration
• Leaking air out of the home is called exfiltration
Energy Audit Tips: plugging the leaks
• Check for holes or cracks around walls, ceilings, windows, doors, light and plumbing
fixtures, switches, and electrical outlets that often leak.
• Check insulation levels in attic, walls, ceilings, floors, basements and crawl spaces
• Check for open fireplace dampers

22. Building Envelope - Insulation
Thermal Resistance (R):
• The effectiveness of insulation is
rated in terms of thermal
resistance, called R-value, which
indicates the resistance to heat
flow.
• Higher R-values mean more
insulating power. The R-value of
thermal insulation depends on the
type of material, its thickness, and
its density.

23. Building Envelope
Types of Insulation
There are several common types of insulation — blanket (batts or rolls), loose fill, foam board
or rigid foam, spray foam and reflective insulation.
Blanket: Most common type of insulation. It
can be hand cut and trimmed to fit. Usually
made of fiberglass, mineral wool, plastic fiber
or natural fibers
Loose-fill: Usually made of small particles of
fiberglass, rock wool, or cellulose. Good for
retrofits and hard-to-reach areas.

24. Building Envelope
Types of Insulation
Foam board or rigid foam: Rigid panels of
insulation. This type of insulation can be used
to insulate almost any part of your home.
Sprayed Foam: This type of insulation can be Reflective: Fabricated from aluminum
sprayed, foamed-in-place, injected or poured. foils with different backings such as
Its ability to fill the smallest spaces gives it cardboard. This type of insulation is
twice the R-value per inch when compared to typically used between wood rafters, floor
traditional batt insulation joists or wall studs

32. Operating Your HVAC Efficiently
HVAC Thermostat Control: A thermostat is a temperature-sensitive switch that controls a
space conditioning unit or system, such as a furnace or air conditioner, or both.
Heating Season (winter): keeping the temperature a little lower will save energy. Energy savings
will depend on how much you lower the thermostat settings and how cold the climate is.
Cooling Season (summer): raising the temperature a little higher will save energy. Energy
savings will depend on how much you raise the thermostat settings and how hot the climate is.

40. Home Appliances – Refrigerators and Freezers
• Refrigerators consume about 18% of all
electricity in a typical Californian home .
• Refrigerators have become much more
efficient in the past 20 years, using 60% less
electricity on average than 20-year-old
models.
• If you have an old, inefficient refrigerator, you
may be paying $280 a year in electricity in
areas with high electricity rates. A new, more
efficient model will lower your electric bill and
save you money, which in turn will offset the
cost of purchasing a new refrigerator.

41. Home Appliances – Clothes Washers
• A typical household clothes washer can cost
as much as $1,500 to operate over its lifetime
(12 years).
• Almost 90% of all energy used in operating a
washing machine goes towards heating the
water.
• By investing in a new, efficient front- or top-
loading washer, homeowners can
dramatically save energy, water and money.
• An ENERGY STAR qualified clothes washer
can save you up to $875 in energy and water
costs over the life of the machine.
41
41

42. Home Appliances – Dishwashers
• Approximately 80% of the energy used by
dishwashers goes toward heating the water.
• New dishwasher designs have reduced water use
• Consumers can save $25 to $35 a year in energy
costs by replacing a 10-year-old dishwasher with an
ENERGY STAR qualified model, and save more than
1,000 gallons of water per year.
• The average dishwasher lasts up to 12 years
